U.S. Slaps Extra Taxes on Chinese L-Lysine
Published Date: 7/23/2026
Notice
Summary
The U.S. Department of Commerce found that Chinese producers of L-lysine, a key animal feed ingredient, got unfair government help during 2024. Because of this, the U.S. will add extra taxes (countervailing duties) on these imports starting July 23, 2026, to keep things fair for American businesses. This means companies buying L-lysine from China will pay more, helping U.S. producers compete better.
Analyzed Economic Effects
4 provisions identified: 0 benefits, 2 costs, 2 mixed.
Countervailing Duties May Apply to Imports
Commerce found that subsidies were provided to Chinese producers of L-lysine for the period January 1, 2024 through December 31, 2024. If the U.S. International Trade Commission (ITC) also finds injury, Commerce will issue a countervailing duty (CVD) order and require cash deposits of estimated duties starting with the entries covered by the suspension of liquidation, effective July 23, 2026.
Specific Duty Rates Assigned to Producers
Commerce assigned estimated ad valorem countervailing duty rates for the period January 1, 2024 through December 31, 2024 as follows: Inner Mongolia Eppen Biotech Co. Ltd. — 48.21 percent; Helionjiang Wanli Runda Biotechnology Co., Ltd. — 82.11 percent (AFA); Shouguang Golden-land Industry & Trading Co Ltd — 82.11 percent (AFA); All Others — 48.21 percent. These percentage rates are the estimated subsidy rates Commerce used in this final determination.
CBP Cash Deposits and Suspension Dates Specified
Commerce instructed U.S. Customs and Border Protection (CBP) to collect cash deposits and suspend liquidation for entries of subject merchandise entered, or withdrawn from warehouse, for consumption on or after January 22, 2026. Commerce instructed CBP to discontinue the suspension for entries on or after May 22, 2026, but to continue suspension for entries on or before May 21, 2026. If the ITC finds no injury, all deposits will be refunded.
Scope Covers All Animal-Feed Grade Lysine Forms
The investigation scope covers animal feed grade L-lysine in all forms, including lysine monohydrochloride (lysine HCL), lysine sulfate, and liquid lysine, as well as coated/encapsulated forms and lysine combined with other products; HTSUS subheadings listed include 2922.41.0090 and others.
